To all whom- "it may concern:

- Be it lIIl a that I, LOUIS LAzAIiE AU- ousrs Should, a citizen ofFrance, residing 49 Rue lie'l'tittc, Paris, in the Republic France, haveinvented new and useful lmprovements in Rotary Engines, of which thefollowing is o specification.

This invention relates to an improved construction of a motor of thekind having redial cylinders turning around a fixed axle In thisimproved motor, the casing is constituted by an annular steel ringprovided with holes in which are fitted cylinders with cooling flangesand supported onthe casing by means of an elasticring placed in. anannular groove on the cylinder and bearing on an adjusted correspondingseat of the internal surface of the casing. The cylinders are secured onsaid casing by means of keys with two fist surfaces, each maintainingtwo cylinders.

The annexed drawing represents a form of the improved motor hovingsevencylinders.

Figure 1 is a front elevation of the motor, partly in section. F 1g. 2is a section alone;

the line 2-2 of Fig. 1 cylinder being shown in elevation and the heybeing o1nit ted. Fig. 3 is an enlarged detail View show ing theconnection of the casing and-,cylin dcrs. Fig. l is an enlarged det ilView in section along the line 44: of

The casing of the motor is constituted. by a ring of steel 1 closed bytwo checks 2, '8, carrying the stutling homes through which the finedshaft or crank a passes. The ring 1 is provided with holes spaceduniformly on its circumference, in which are titted the cylinders at, 4:carrying the cooling flanges 5. The inner end of each cylinder isprovided with an annular groove 6 so that for mounting each cylinder onthe casing it may he fitted from the outside of the casing into thecorresponding hole. A divided or elastic ring 7 may then be fittedwithin thecasing on the end of the cylinder, said elastic rincoiitrsctin mils: slot 6 en on aging in the same while extending outwardy from the outer surface of the cyxiiiderw The cylinder 4 carrying therm the ring bears on the corresponding adwhcn in front of the anmay thenbe drawn outwardly untiljusted seat on the inner wall of the steel thatmade by the under faces of the adjacent elastic rings 7 as shown'insection in Fig. 3.. The that faces of the keys are inclined on the axisof the cylindrical body so that the key has a section decreasing fromend to end as shown in Fig l. Cylindrical bores 10 are formed in thering 1 (Figs. 2 and l) for receiving the keys 8, each bore being solocated in the ring 1 be tween two adjacent cylinders that the elasticrings 7 of said cylinders project into said bores as shown in Fig. 3.The axis of the bores 10 is so inclined on. the axis of the ring 1 thatwhen two adjacent cylinders 41: are fitted radially into the holes inthe ring 1, if a key 8 is forced. into the corresponding bore 10 betweenthe two cylinders the flat faces of the key will bear against the underfaces of-the elastic rings 7, respectively, the

so as to secure the cylinders firmly in position. Each key serves forfixing two adjacent cylinders. It can easily be understood that underthe action of centrifugal force the rings 7 are forcibly applied on thecorresponding seats of the casing and in proportion to the speed ofrotation of the motor. The prevention of play is obtained by furthersinking the keys.

The mountin and dismounting of the parts is extreme y 'simple'and reuoidand the whole is perfectly rigid andithe central. chamber is both gasand oil tight.

Having now described my invention, what I claim as new anddesireltovseciire by Letters Patent is:

In a rotary engine-with redial cylinders the combinstion' with .2, ring1' having a plurality of" radial holes, annular seats formed inwardlyabout-said verse bores 10 intermediate thersdialholes,

of cylinders 4: fitted" in thera dial holes tmd provided at one end withan'annular groove. 6,. elastic rings *7 engagmgfsmd grooves;-

holes end transbearing against the annular seats of the name to thisspecification in the presence of ring 1,' and projecting into thetransverse two subscribing witnesses.

bores of the ring 1, and keys forced into said bores against the elasticrings, substan- LOUIS LAZARE AUGUSTE SEQUIN 5 tially as described afidfor the purpose set Witnesses forth. i DEAN 'B. MASON,

In testimony whereof I have signed my ANT INE LAVOIB.
